C語言-判斷迴文數字

有這樣一類數字，它們順着看和倒着看都是相同的數，例如121、656、12321。編寫判斷從鍵盤接收的數字是否爲迴文數字

int reverse(int i) {
    int m, j = 0;
    m = i;
    while (m) {
        j = j * 10 + m % 10;
        m = m / 10;
    }
    return j;
}
int isCircle(int n) {
    int m;
    m = reverse(n);
    if (m == n)
        return 1;
    else
        return 0;
}
int main(int argc, const char *argv[]) {
 int n;
    printf("Type a integer for judging is Circle :\n");
    scanf("%d", &n);
    if (isCircle(n))
        printf("%d is Cirle\n", n);
    else
        printf("%d is not Cirle\n", n);

  return 0;
}

結果：
